Our Future Health is a prospective, observational cohort study of the general adult population of the United Kingdom (UK). The programme aims to support a wide range of observational health research. We gather personal, health and lifestyle information from each participant through a self-completed baseline health questionnaire and at an in-person clinic visit. We will further link this data to other health-related data sets. Participants have also given consent for us to recontact them, for example to invite them to take part in further or repeat data collections, or other embedded studies such as clinical trials.

The Our Future Health programme is currently open to all adults (18 years and older) living in the UK. In July 2022, we started recruiting participants in England and will continue to expand across the rest of the UK. The data we’ve gathered so far (June 2025) includes clinical measurements from 1,324,884 participants.

Additional linked datasets are available:

• ‘Baseline Health Questionnaire Data’ which contains baseline demographic information and responses to our health questionnaire from 1,781,891 participants.
• ‘Linked NHS England Health Records Data which contains linked clinical data from NHS England for 1,527,723 participants.
• ‘Genotype Array Data’ which includes genotype array data on 707,522 variants from a subset of 650,979 participants

The data is stored in the Our Future Health Trusted Research Environment. We de-identify all participant data we gather before it’s available for use. All researchers will need to become registered researchers at Our Future Health and have an approved research study before they're given access to the data.

We aim to collect a variety of data types from up to 5 million adult participants from across the UK. We hope to make more data types available on a quarterly basis.
